However, disadvantages of the coalstoves and boilers comprise complex structure, huge volume, inconvenientadjustment of temperature, high power consumption and high pollution. Asfor the electric heaters and the air-conditioners, although they areconvenient for temperature adjustment, low heat efficiency, highelectricity consumption, small heat radiating area, occupation oflimited indoor space are non-neglectable problems to be solved,moreover, many people feel uncomfortable since heat is provided via airconvection.

This kind of floor realizes convenient adjustmentof temperature, low power consumption and environmental protection,needs no fuel, saves indoor space, and is capable of supplying heat froma sole of a foot to the indoor space.

However, there are some problems with the above-mentioned floor:firstly, the floor is laid along with electric wire to facilitateintegral forming, which causes great difficulty in construction and lowefficiency, moreover, once the floor is damaged, it is difficult to fixand maintain, and dangerous electric leakage often takes place.Secondly, the carbon fiber infrared heat component is not efficientlyutilized since it is embedded under the bottom of the calcium silicatecement guard plate, which severely affects penetrability of infraredray, and leads to attenuation in thermal infrared radiation and loss ofhealth functions. Thirdly, the floor is globally electrified, and it isimpossible to flexibly implement local control of electricity asrequired, which causes unnecessary heat loss and influencesenergy-saving effect. Fourthly, the floor is disposable, once failureoccurs, the floor as a whole will be damaged, which causes high usingcost and environmental pollution. Fifthly, a top of the floor is only acement guard plate, and a decoration layer needs to be laid on thebottom thereof, which increases a thickness of the floor and bringsabout extra burden to a user. Finally, due to attenuation in thermalinfrared radiation and slow heat conduction, temperature rise of thefloor is very slow and time-consuming, which decreases heat efficiencyand influences heating effect.

Advantages of the invention are as follows:

Comfortable Heating Supply

The invention implements low-power and large-area heating supply in amanner of low-temperature radiation instead of air heating, and preventsdrying and dust caused by convective heating supply. Heat radiates anddissipates from the ground and acts on a sole and a body of a user, andmakes the user feel comfortable and relaxed. A mechanism of thelow-temperature radiation is to make human body and indoor objectsabsorb energy first, and temperature thereof will rise, and then to makethem radiate energy, and indoor temperature will uniformly rise. In thissituation, actual temperature of human body is higher than airtemperature, and thus the user may feel warm and comfortable. Moreover,all rooms are equipped with independent temperature controllers, usersare capable of adjusting indoor temperature as required, and thuspersonalized requirement of the users are realized.

Healthy Heating Supply

In a power-on state, the floor of the invention generates far-infraredlight wave with a wavelength centralized between 6 to 16 μm, so as tocause human deep cells to moderately resonate. If a user stays in thisenvironment for a long period of time, his human microcirculation willbe improved, metabolism will be promoted, cell vitality will bestrengthened and nervous and endocrine systems will be adjusted.Moreover, the invention is also capable of promoting blood flow tosmooth meridians and collaterals and improving human immunity.

Safe Heating Supply

The floor of the invention uses materials with good insulationcharacteristics, a surface resistance and a volume resistance of thefloor are greater than 1 MΩ, and electrical breakdown strength thereofis greater than 500V, which make the floor very safe and reliable. Evenif electric leakage occurs in use, there will be no electric shockaccident.

Environment-Protection Heating Supply

The floor of the invention does not generate noise during operation. Byusing electricity as a clean energy, air pollution caused by traditionalboilers is prevented. By way of electron impact and friction heat, highlight or electromagnetic pollution is not generated.

Economic and Energy Saving

Since an electric heat conversion rate of the floor of the invention isabove 99% and heating materials are close to the surface of the floor,heat may be adequately dissipated to a room. Average power consumptionof the floor is 15-25 W/m2 (architectural area). By way of anintelligent temperature controller, the floor is capable of switching onor off heating at any time in divided periods or rooms, or commonmovable raised floors may be used in certain unnecessary places, thusoperation cost will be significantly reduced.

Convenient Installation

The floor of the invention is easy and convenient for installation.Since heating materials are integrated with the floor, heating anddecoration effects are reached after construction, and thus cumbersomeprocesses caused by separated construction of heating resources andfloorings are eliminated. An installation process of the floor of theinvention is the same as that of a common movable raised floor exceptfor connection of electric appliances and wires.

Fast Heating

2-3 minutes after being powered on, the floor begins heating and heat isquickly dissipated into a room. In cold weather, when people go home,they do not need to wait and will feel warm soon.

Space Saving and Reduced Construction Cost

The floor of the invention integrates a heating function with adecoration function and traditional flues and radiators are no longerneeded, which increases usable are of a room, makes the room easy fordecoration and reduces cost spent on decoration. Meanwhile, since noheating facility (such as a boiler or a pipe) is used, a storey heightof a building can be decreased by 5-6 cm, and thus construction cost iscorrespondingly reduced.
